Chlorophyll-a, Orbview-2 SeaWiFS, R2018.0, 0.1°, Global, 1997-2010 (8 Day Composite)

NASA GSFC Ocean Color Web distributes science-quality chlorophyll-a
concentration data from the Sea-viewing Wide Field-of-view Sensor (SeaWiFS)
on the Orbview-2 satellite. This version is the 2018.0 Reprocessing (R2018.0).
https://oceancolor.gsfc.nasa.gov/reprocessing/r2018/seawifs/

The SeaWiFS instrument was launched by Orbital Sciences Corporation on the
OrbView-2 (a.k.a. SeaStar) satellite in August 1997, and collected data from
September 1997 until the end of mission in December 2010. SeaWiFS had 8
spectral bands from 412 to 865 nm. It collected global data at 4 km
resolution, and local data (limited onboard storage and direct broadcast)
at 1 km. The mission and sensor were optimized for ocean color measurements,
with a local noon (descending) equator crossing time orbit, fore-and-aft
tilt capability, full dynamic range, and low polarization sensitivity.

美国国家航空航天局戈达德太空飞行中心海洋色彩网络分发由轨道科学公司于1997年8月发射在OrbView-2（又称SeaStar）卫星上的海洋观测宽视场传感器（SeaWiFS）收集的具有科学品质的叶绿素-a浓度数据。本版本为2018.0重处理版（R2018.0）。详情请见：https://oceancolor.gsfc.nasa.gov/reprocessing/r2018/seawifs/

SeaWiFS仪器由轨道科学公司于1997年8月搭载OrbView-2卫星发射升空，并从1997年9月到任务结束的2010年12月持续收集数据。SeaWiFS具有从412至865纳米的8个光谱波段。该仪器以4公里分辨率的全球数据，以及受限于机载存储和直接广播的1公里分辨率局部数据进行数据采集。任务和传感器针对海洋色彩测量进行了优化，包括当地正午（下行）赤道穿越时间轨道、前后倾斜能力、全动态范围和低偏振敏感性。
